Micromagnetic Simulation of Round Ferromagnetic Nanodots with Varying Roughness and Symmetry

Pia Steinmetz et al.

Summary: This study investigates the influence of angular-dependent roughness of the edges created by building nanoparticles from small cubes on hysteresis loops and magnetization reversal processes in different shaped nanodots. It is found that for the thinnest ring, there is significant dependence of the transverse magnetization component on the field orientation.

Exchange Bias in Thin Films-An Update

Tomasz Blachowicz et al.

Summary: Exchange bias is an effect that occurs in coupled ferromagnetic/antiferromagnetic materials, resulting in a shift of the hysteresis loop and increased coercivity, potentially creating asymmetric hysteresis loops. Despite some drawbacks and unanswered questions in existing models, exchange bias systems are widely used in hard drive read heads and spintronics applications.

Asymmetric Hysteresis Loops in Structured Ferromagnetic Nanoparticles with Hard/Soft Areas

Joscha Detzmeier et al.

Summary: Micromagnetic simulations on sputtered nanoparticles with different structures at zero temperature reveal that small deviations in systems due to random anisotropy orientations in different grains can lead to significant deviations in magnetization reversal processes and hysteresis loops, as well as distinctly asymmetric, horizontally shifted hysteresis loops in purely ferromagnetic nanoparticles.
